SKREEM Programming: Notes
When a Powertrain Control Module (PCM) for a gasoline engine, or an Engine Control Module (ECM) for a diesel engine and the Sentry Key Remote Entry Module (SKREEM) (also known as the Wireless Control Module/WCM) on vehicles equipped with the Sentry Key Immobilizer System (SKIS) are replaced at the same time, perform the following steps in order:
NOTE:
If the PCM and the SKREEM are replaced at the same time, program the PCM VIN into the PCM first.
- If applicable first replace the PCM/ECM with the original WCM still connected to the vehicle.
- Using the appropriate service information program the new PCM/ECM. (This will ensure the Secret Key Transfer from the original WCM into the new PCM/ECM).
- Now replace and program the WCM. This will retain the Secret Key from the PCM/ECM back into the new WCM.
- With the scan tool, select Miscellaneous Functions, WCM/Wireless Control Module. Then select the desired procedure and follow the display on the scan tool.
- If the vehicle is equipped with Tire Pressure Monitoring System program the Placard Pressure Values into the WCM/SKREEM.
- Ensure all the customer's keys have been programmed into the new module if necessary.
NOTE:
If the original keys do not successfully program to the new SKREEM after the proper procedures are followed correctly, programming new keys will be necessary.
